* master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-2.6:
  Revert "Driver core: let request_module() send a /sys/modules/kmod/-uevent"
  Driver core: fix error by cleanup up symlinks properly
  make kernel/kmod.c:kmod_mk static
  power management: fix struct layout and docs
  power management: no valid states w/o pm_ops
  Driver core: more fallout from class_device changes for pcmcia
  sysfs: move struct sysfs_dirent to private header
  driver core: refcounting fix
  Driver core: remove class_device_rename

+ *	If not assigned, all suspend states are advertised as valid

+ *
+ * @prepare: Prepare the platform for the given suspend state. Can return a

+ *
+ * @enter: Enter the given suspend state, must be assigned. Can return a

+ * @finish: Called when the system has left the given state and all devices

+ *
+ * @pm_disk_mode: Set to the disk method that the user should be able to
+ *	configure for suspend-to-disk. Since %PM_DISK_SHUTDOWN,
+ *	%PM_DISK_REBOOT, %PM_DISK_TEST and %PM_DISK_TESTPROC

+ *	callback is called after state has been restored. All
